Check when will be the fifth Hirji month of Jumada-al-Oola 1438 in your residence. The Hijri Calendar is a lunar one, meaning that months begin when the first crescent of a new moon is sighted.
And since this type of calendars is 11 to 12 days shorter than the solar year, Jumada-al-Oola and all Hijri months migrate throughout the seasons.
The Astronomical New Moon (conjunction) is on Saturday, January 28, 2017 at 0:06 UTC. On that day, the moon can be seen with difficulty in parts of the Americas.
On Sunday, January 29, 2017, the new crescent can be seen in the whole world except New Zealand.
This means that Jumada-al-Oola is expected to start on Sunday the 29th of January.
